Disgusted by Precious Modiro’s Poor level of customer service - Rivonia Boulevard Checkers

Yesterday I went in to the Checkers in Rivonia with the intention of getting a few items enroute to my next appointment. I shopped and got to the till where the transaction went off from my bank account but grocery refused with. Precious Modiro insisted that she is not giving the grocery because the money would automatically be reversed in my account within 24 hours. When seeing how much time I had lost I offered to pay again since the money was going to be reversed and she said even that was not possible. I was then forced to leave the grocery, despite my money being withdrawn from my account. Before I left, Precious took my details and said the money will reflect within 24 hours and that she would call within 24 hours to confirm and took my details. Fast forward to after 24 hours, my money is still not returned into my account and I have not received from Precious. I call in today and and am confronted by a very rude Preciou who tells me that she has been busy and that I must come in to get my money AFTER SHE HAD ADVISED THAT IT WOULD AUTOMATICALLY BE REVERSED IN MY ACCOUNT! She then adds by saying that I must submit my bank statement to prove the transaction did not take lace after saying she would trace from their records if the transaction goes through. Now why would I ever give a bank statement to a supermarket - something so personal, then now have to be the one to go in and fight or motivate to get my money back? With the way Precious gives customers the run around, it is clear she is clueless on how the systems work and gives the customers the run around. I have been disgusted by how she has dealt with me and other customers, especially those they chased all the way to the parking area to collect the grocery. Shoprite Rivonia has really lost me as a customer - the customer care is non-existent. Please can my money be reversed as promised and we can call it a day!
